HEASA 2023 was the tenth conference in the annual series "High Energy Astrophysics in Southern Africa". Its goal was to bring together scientists from the southern African region, the African continent, and around the world with an interest in high-energy astrophysical phenomena. Topics discussed included theoretical, multi-wavelength, and multi-messenger observational aspects of astrophysical sources (e.g. active galactic nuclei (AGNs), galaxy systems, gamma-ray bursts (GRBs), X-ray/gamma-ray binaries, supernovae and supernova remnants, neutron stars, pulsars and pulsar wind nebulae, cataclysmic variables (CVs)) as well as modern aspects of astro-particle physics.

HEASA 2023 was held during the period of 5 - 9 September 2023 as a hybrid conference in Mtunzini, KwaZulu-Natal, South Africa. It was sponsored by the Department of Science and Innovation (DSI) and the National Research Foundation (NRF) of South Africa through the South African Gamma-Ray Astronomy Programme (SA-GAMMA).
